Avaliação Econômica dos Benefícios dos Macronutrientes em Diferentes Povoamentos de Bracatinga

Abstract

A bracatinga é uma espécie nativa, com papel importante na economia de pequenos proprietários. Dessa forma, o presente trabalho foi desenvolvido com o intuito de quantificar o conteúdo de macronutrientes presentes nos diferentes componentes da biomassa aérea de bracatingais nativos e, posteriormente, valorar economicamente os resíduos florestais mantidos na área após a exploração. Os dados foram coletados em 304 parcelas temporárias, com diferentes idades, em povoamentos de bracatinga. Em ordem decrescente, os valores de macronutrientes encontrados na parte aérea dos bracatingais seguiram a sequência: N > Ca > K > Mg > P. Após a exploração da lenha, restaram como remanescentes nas áreas os resíduos contendo uma média geral de 32% de Ca, 26% de Mg, 39% de N, 34% de P e 19% de K, com um equivalente monetário médio de fertilizantes (em reais.ha-1) variando de 303,56 a 1.140,78, dependendo do local e da classificação de sítio da propriedade.
